How to fix an electric shower

People love an electric shower. The water is instantly hot, and the flow remains constant, as does the temperature. It sounds ideal, and it is, at least until you run into a problem. More complex problems with an electric shower will require a plumber or electrician, unless you’re well versed in both. However, it’s quite possible to do some basic troubleshooting yourself.

People love an electric shower. The water is instantly hot, and the flow remains constant, as does the temperature. It sounds ideal, and it is, at least until you run into a problem. More complex problems with an electric shower will require a plumber or electrician, unless you’re well versed in both. However, it’s quite possible to do some basic troubleshooting yourself.


Step One

Shower Doesn’t Work - If the shower won’t turn on when you press the button, then the problem might well be in the circuit breaker. Turn the shower off again and check the breaker box. An electric shower should have its own circuit. Check to see that the breaker is on. If not, flip it on and try running the shower to see if it flips off again.


Step Two

Shower Cuts Off - If the electric shower cuts off after about a minute of running normally, the problem might not be in the electrical system. Try removing the shower head (it will unscrew) and then tip it upside down over a bowl. You should find some limescale tipping out of the shower head. Buy some limescale remover and place the shower head in it, holes down. This will remove the limescale that’s clogging the shower head. Remove the shower head and wash through with cold water to take out all the debris. Screw the shower head back on and try the shower again. With no more clogging the shower should run normally. What has happened is that, as the water stays too long in the heater, the cut off kicks in and stops the shower.


Step Three

Low Pressure - If you suddenly encounter low pressure in the electric shower, the problem can be in the filter of the electric shower. To access this, you need to go into the unit where it comes off the water line. Look at your owner’s manual to locate the part. With the water turned off at the mains, remove the filter and clean it. The chances are that it’s become clogged, causing the low water pressure.


Step Four

Cold Water Leak - If you find that your unit is leaking cold water, open up the unit. You will need to find the stabilizer valve. After a while, these will need to be replaced. Make sure the circuit breaker for the electric shower is off and that the water is also off. Purchase a new stabilizer valve for your unit, making sure you have the correct one. Remove the old valve and fit the new one. Switch the water and electricity back on. This should eliminate the cold water leak from the electric shower.


Step Five

Flow Rate - In winter, you want a hot shower so you turn up the temperature of the shower. As the water coming into the shower is cold and is heated in the shower, the flow rate will be low. This leads to a low flow rate in the winter. Don’t be worried by this, as it’s perfectly normal. In this instance, you should simply increase the flow rate.
